Chess Series Chalks Up Another Draw

NEW YORK — Observers said it was the most exciting game of the Professional Chess Association world championship match so far, but in the end the combatants agreed to yet another draw Tuesday.

World champion Garry Kasparov of Russia, playing with the white pieces, offered challenger Viswanathan Anand of India the draw after his 28th move.

The two tested each other with a variation of the Ruy Lopez or Spanish opening. As the game progressed, Anand brought matters to life with his 20th turn, exchanging one of his rooks for a less valuable knight and a pawn. The challenger later explained that the exchange was necessary to avoid defeat. Each player now has 3 points in the series.
